no automatic mount of USB 3TB external drive

Hey all,

I have a 3TB Seagate USB drive (PN: 1DXAP3-500) I want to use to backup my RN104 (on 6.2.0).

It is formatted to NTFS, and was just checked with Windows and has no problems.

When I plug it in, nothing shows up.

I ssh into the machine, fdisk sees it.

Disk /dev/sde: 3000.6 GB, 3000592977920 bytes
255 heads, 63 sectors/track, 45600 cylinders, total 732566645 sectors
Units = sectors of 1 * 4096 = 4096 bytes
Sector size (logical/physical): 4096 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes
Disk identifier: 0x6e697373

This doesn't look like a partition table
Probably you selected the wrong device.

   Device Boot      Start         End      Blocks   Id  System

Partition table entries are not in disk order

So I try to manually mount it with the options I copied from mounting a different NTFS drive that does automount:

mount -t ufsd /dev/sde /root/usbdrive -o rw,noatime,nodiratime,nls=utf8,fmask=0,dmask=0

And it works fine.

But why doesn't the system automatically mount it?

Is it because of the other partitions on the drive?

Are there any issues with using the drive in this manually operated manner? Even after the manual mount, nothing shows up on the admin page.
